Description

本発明は、複写機や電子写真プリンタ等の電子機器におけるフェライトコア等の部材を固定する固定具に関するとともに、該固定具を具備する電子機器に関する。   The present invention relates to a fixture for fixing a member such as a ferrite core in an electronic device such as a copying machine or an electrophotographic printer, and also relates to an electronic device including the fixture.

従来、電子機器等において発生する電気的ノイズを軽減するために、フェライトコアをケーブルに装着することが一般に行われている。フェライトコアを固定する方法としては、例えば、特開２０００−１７３８２７号公報に開示される方法がある。これは、フェライトコアの中空部にケーブルを貫通させた状態でフェライトコアを収納ケースに収納し、その収納ケースの下面に設けた係合部の爪部を電子機器筐体または基板に係合させることによりフェライトコアを固定するというものである。
特開２０００−１７３８２７号公報 Conventionally, a ferrite core is generally attached to a cable in order to reduce electrical noise generated in an electronic device or the like. As a method for fixing the ferrite core, for example, there is a method disclosed in Japanese Patent Laid-Open No. 2000-173827. This is because the ferrite core is accommodated in the storage case with the cable passing through the hollow portion of the ferrite core, and the claw portion of the engaging portion provided on the lower surface of the storage case is engaged with the electronic device casing or the substrate. In this way, the ferrite core is fixed.
JP 2000-173827 A

しかしながら上記従来のフェライトコア固定構造においては、フェライトコアを収納する収納ケースに固定用の係合部が設けられているので、フェライトコアを固定したい場所に収納ケースごと固定しなければならない。しかしながらフェライトコアを固定したい場所が非常に狭い場合には収納ケースを固定できない。このため収納ケースを固定できるだけのスペースのある場所を選んでフェライトコアを固定していた。   However, in the conventional ferrite core fixing structure described above, since the fixing engaging portion is provided in the storage case for storing the ferrite core, the storage case must be fixed to the place where the ferrite core is to be fixed. However, if the place where the ferrite core is to be fixed is very narrow, the storage case cannot be fixed. For this reason, the ferrite core was fixed by selecting a place with enough space to fix the storage case.

上記構成の本発明によれば、保持部で部材を動きを規制しつつ保持し、保持部と同一平面上に形成された被固定部で取付け対象に固定されるので、部材を固定する場所として広いスペースがなくても固定可能である。   According to the present invention having the above configuration, the member is held while restricting movement by the holding portion, and is fixed to the mounting target by the fixed portion formed on the same plane as the holding portion. It can be fixed without a large space.

以下、本発明を実施するための形態を図面に従って説明する。以下に説明する各実施の形態では、中空部を有する部材としてフェライトコアを例にとって説明する。図１は本発明の第１の実施の形態のフェライトコア固定具を示す斜視図、図２はフェライトコアを示す正面図、図３は第１の実施の形態のフェライトコア固定具を示す正面図である。   DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In each embodiment described below, a ferrite core will be described as an example of a member having a hollow portion. 1 is a perspective view showing a ferrite core fixture according to the first embodiment of the present invention, FIG. 2 is a front view showing the ferrite core, and FIG. 3 is a front view showing the ferrite core fixture of the first embodiment. It is.

図１において、フェライトコア固定具１は、フィルムシート状の平板形をした弾性部材から形成され、保持部２と被固定部３から構成される。保持部２は、溝部４を間にして形成された２つの腕部５、６を有し、腕部５、６の形状は互いに線対称に形成されている。腕部５、６の先端側（図における上側）にはそれぞれ面取り部５ａ、６ａおよびカギ爪部５ｂ、６ｂが形成され、腕部５、６の中央外側には溝部４と平行な嵌合部５ｃ、６ｃが形成されている。嵌合部５ｃ、６ｃの下側にはそれぞれ棚部５ｄ、６ｄが形成されている。   In FIG. 1, a ferrite core fixture 1 is formed from a film sheet-like flat plate-like elastic member, and includes a holding portion 2 and a fixed portion 3. The holding part 2 has two arm parts 5 and 6 formed with the groove part 4 therebetween, and the shapes of the arm parts 5 and 6 are formed symmetrically with respect to each other. Chamfered portions 5a and 6a and key claw portions 5b and 6b are formed on the distal end sides (upper side in the figure) of the arm portions 5 and 6, respectively. 5c and 6c are formed. Shelves 5d and 6d are formed below the fitting portions 5c and 6c, respectively.

被固定部３には、フェライトコア固定具１を取付け対象に固定するためのネジ孔７が形成されている。ネジ孔７は保持部２の溝部４の延長線上から片側へずれた位置に形成されている。   A screw hole 7 for fixing the ferrite core fixture 1 to an attachment target is formed in the fixed portion 3. The screw hole 7 is formed at a position shifted to one side from the extension line of the groove portion 4 of the holding portion 2.

本実施の形態のフェライトコア固定具１の材質はポリエチレンテレフタラート（ＰＥＴ）からなっている。しかしながら材質としては、ＡＢＳ樹脂、エンジニアリングプラスチック等プラスチック材料であればよく、さらに同等の性質を有していれば金属製のフィルム等でも構わない。   The material of the ferrite core fixture 1 of the present embodiment is made of polyethylene terephthalate (PET). However, the material may be a plastic material such as ABS resin or engineering plastic, and may be a metal film or the like as long as it has equivalent properties.

図３はフェライトコアの中空部にフェライトコア固定具１を挿通する様子を示す。図２、図３において、フェライトコア１０は扁平の長円形の中空部１１を有している。中空部１１の幅（長径）Ｌ１は２０ｍｍ、中空部１１の厚さ（短径）ｔは１．０ｍｍである。なおフェライトコア固定具１の厚さは０．５ｍｍに形成され、後述するケーブルの厚さは０．３ｍｍに設定されている。   FIG. 3 shows a state in which the ferrite core fixture 1 is inserted through the hollow portion of the ferrite core. 2 and 3, the ferrite core 10 has a flat oval hollow portion 11. The width (major axis) L1 of the hollow part 11 is 20 mm, and the thickness (minor axis) t of the hollow part 11 is 1.0 mm. In addition, the thickness of the ferrite core fixture 1 is formed to 0.5 mm, and the thickness of the cable described later is set to 0.3 mm.

ここでフェライトコア固定具１とフェライトコア１０の中空部１１との寸法関係について説明する。フェライトコア固定具１の保持部２の最大幅、即ち、カギ爪部５ｂからカギ爪部６ｂまでの距離Ｌ２は、フェライトコア１０の中空部１１の幅Ｌ１よりも大きく設定されている。フェライトコア固定具１の腕部５、６は、間に溝部４が形成されているために、互いに接近する方向に接触するまで撓み可能となっている。腕部５、６が互いに接触したとき（二点鎖線で示す状態になったとき）のカギ爪部５ｂからカギ爪部６ｂまでの距離Ｌ３は、中空部１１の幅Ｌ１よりも小さくなるように溝部４の幅Ｌ４が設定されている。   Here, the dimensional relationship between the ferrite core fixture 1 and the hollow portion 11 of the ferrite core 10 will be described. The maximum width of the holding part 2 of the ferrite core fixture 1, that is, the distance L2 from the key claw part 5b to the key claw part 6b is set to be larger than the width L1 of the hollow part 11 of the ferrite core 10. Since the groove portions 4 are formed between the arm portions 5 and 6 of the ferrite core fixture 1, the arm portions 5 and 6 can be bent until they come into contact with each other in the approaching direction. The distance L3 from the lock claw portion 5b to the lock claw portion 6b when the arm portions 5 and 6 are in contact with each other (when the arm portions 5 and 6 are in the state indicated by the two-dot chain line) is smaller than the width L1 of the hollow portion 11. A width L4 of the groove 4 is set.

即ち、Ｌ１＜Ｌ２、Ｌ１＞Ｌ３、Ｌ３＝Ｌ２−Ｌ４が成り立つようにそれぞれの幅を設定している。   That is, the widths are set so that L1 <L2, L1> L3, and L3 = L2−L4.

また嵌合部５ｃから嵌合部６ｃまでの距離Ｌ５は、Ｌ２よりも短く、中空部１１の幅Ｌ１とほぼ同じ寸法か若干大きく設定されている。このように寸法設定することにより、この嵌合部５ｃ、６ｃがフェライトコア１０の中空部１１に挿通したときに、嵌合部５ｃ、６ｃと中空部１１の外周との間にガタツキがなくなる。また棚部５ｄから棚部６ｄまでの距離Ｌ６は、中空部１１の幅Ｌ１よりも大きく設定されている。   The distance L5 from the fitting part 5c to the fitting part 6c is shorter than L2, and is set to be approximately the same as or slightly larger than the width L1 of the hollow part 11. By setting the dimensions in this way, when the fitting portions 5 c and 6 c are inserted into the hollow portion 11 of the ferrite core 10, there is no backlash between the fitting portions 5 c and 6 c and the outer periphery of the hollow portion 11. The distance L6 from the shelf 5d to the shelf 6d is set to be larger than the width L1 of the hollow portion 11.

次に第１の実施の形態におけるフェライトコアを固定する動作を説明する。図４はフェライトコア固定具の保持部がフェライトコアの中空部に挿通された状態を示す。図３において、フラットケーブル（図示せず）をフェライトコア１０の中空部１１に貫通させた後、フェライトコア１０の中空部１１にフェライトコア固定具１の保持部２を挿通させる。   Next, the operation of fixing the ferrite core in the first embodiment will be described. FIG. 4 shows a state where the holding portion of the ferrite core fixture is inserted through the hollow portion of the ferrite core. In FIG. 3, after a flat cable (not shown) is passed through the hollow portion 11 of the ferrite core 10, the holding portion 2 of the ferrite core fixture 1 is inserted into the hollow portion 11 of the ferrite core 10.

まずフェライトコア固定具１の面取り部５ａ、６ａをフェライトコア１０の中空部１１の両端部に当接させ、この状態から保持部２を中空部１１に押し込む。この押し込み動作により腕部５、６は互いに接近する方向に撓み、図３に二点鎖線で示す互いに接触した状態になる。この状態で保持部１１に挿通可能となり、両腕部５、６は中空部１１内に入り込む。   First, the chamfered portions 5 a and 6 a of the ferrite core fixture 1 are brought into contact with both ends of the hollow portion 11 of the ferrite core 10, and the holding portion 2 is pushed into the hollow portion 11 from this state. By this pushing operation, the arm portions 5 and 6 are bent in a direction approaching each other, and are brought into contact with each other as indicated by a two-dot chain line in FIG. In this state, the holding portion 11 can be inserted, and both the arm portions 5 and 6 enter the hollow portion 11.

カギ爪部５ｂ、６ｂが中空部１１を通過すると、両腕部５、６の復元力により、図４に示すように、両腕部５、６は互いに離れて元の状態に復帰する。これによりカギ爪部５ｂ、６ｂ間の距離が広がり、保持部２が中空部１１から抜けない状態になる。このとき、嵌合部５ｃ、６ｃ間の距離Ｌ５が中空部１１の幅Ｌ１よりも若干大きく設定されている場合には嵌合部５ｃ、６ｃが中空部１１の外周に圧接し、ガタツキがなくなる。なお嵌合部５ｃ、６ｃの長さ（カギ爪部５ｂ、６ｂから棚部５ｄ、６ｄまでの距離）はフェライトコア１０の長さより若干長く設定してあり、フェライトコア１０はカギ爪部５ｂ、６ｂから棚部５ｄ、６ｄ間の嵌合部５ｃ、６ｃで保持される。   When the key claws 5b and 6b pass through the hollow portion 11, the arms 5 and 6 are separated from each other and return to the original state by the restoring force of the arms 5 and 6 as shown in FIG. As a result, the distance between the key claws 5b and 6b is increased, and the holding portion 2 is prevented from being removed from the hollow portion 11. At this time, when the distance L5 between the fitting portions 5c and 6c is set to be slightly larger than the width L1 of the hollow portion 11, the fitting portions 5c and 6c are pressed against the outer periphery of the hollow portion 11 and there is no backlash. . Note that the length of the fitting portions 5c and 6c (the distance from the key claw portions 5b and 6b to the shelf portions 5d and 6d) is set slightly longer than the length of the ferrite core 10, and the ferrite core 10 has the key claw portion 5b, It is hold | maintained by the fitting parts 5c and 6c between the shelf parts 5d and 6d from 6b.

フラットケーブル１２を貫通したフェライトコア１０がフェライトコア固定具１により保持された状態を図５、図６に示す。両図において、フラットケーブル１２およびフェライトコア１０はフェライトコア固定具１により保持され、このとき被固定部３のネジ孔７はフラットケーブル１２から外れた位置にあり、フェライトコア固定具１を取付け対象に固定する際にフラットケーブル１２が邪魔になることはない。なおフェライトコア１０およびフェライトコア固定具１はフラットケーブル１２に対して移動可能である。   The state where the ferrite core 10 penetrating the flat cable 12 is held by the ferrite core fixture 1 is shown in FIGS. In both figures, the flat cable 12 and the ferrite core 10 are held by the ferrite core fixture 1, and at this time, the screw hole 7 of the fixed portion 3 is located away from the flat cable 12, and the ferrite core fixture 1 is attached. The flat cable 12 does not get in the way when fixed to the cable. The ferrite core 10 and the ferrite core fixture 1 are movable with respect to the flat cable 12.

次にフェライトコア固定具１の被固定部３に形成されたネジ孔７を使用して取付け対象にフェライトコア固定具１をネジ固定する。取付け対象として電子写真プリンタを例にした場合を図７に一部切り欠いた状態で示す。図７において、電子写真プリンタ２０の操作部ケース２１の内側に操作部基板２２が配置されており、操作部基板２２にはコネクタ２３が具備されている。このコネクタ２３にフラットケーブル１２が接続されている。   Next, the ferrite core fixture 1 is screwed to the attachment target using the screw holes 7 formed in the fixed portion 3 of the ferrite core fixture 1. A case where an electrophotographic printer is taken as an example of the attachment object is shown in a partially cutaway state in FIG. In FIG. 7, an operation unit substrate 22 is disposed inside an operation unit case 21 of the electrophotographic printer 20, and the operation unit substrate 22 includes a connector 23. The flat cable 12 is connected to the connector 23.

プリンタ２０の底部にはコントロール基板２４が配置され、このコントロール基板２４にはコネクタ２５が具備され、フラットケーブル１２はこのコネクタ２５と操作部基板２２のコネクタ２３とを接続する。フェライトコア１０はこのフラットケーブル１２が挿通され、このフェライトコア１０をフェライトコア固定具１が保持している。フェライトコア固定具１は、プリンタ２０の側部のフレーム２６にネジ２７により固定される。図７に示す例の場合、フレーム２６の取付け面は水平で、フェライトコア固定具１はほぼ垂直に折り曲げられた状態でネジ２７により固定されている。   A control board 24 is disposed at the bottom of the printer 20. The control board 24 includes a connector 25, and the flat cable 12 connects the connector 25 and the connector 23 of the operation unit board 22. The ferrite core 10 is inserted with the flat cable 12, and the ferrite core 10 is held by the ferrite core fixture 1. The ferrite core fixture 1 is fixed to the frame 26 on the side of the printer 20 with screws 27. In the case of the example shown in FIG. 7, the mounting surface of the frame 26 is horizontal, and the ferrite core fixture 1 is fixed by screws 27 in a state of being bent substantially vertically.

フェライトコア１０およびフェライトコア固定具１をフラットケーブル１２に対して移動することにより、最適な位置にフェライトコア１０を固定することができる。またフェライトコア固定具１の被固定部３の長さ又は形状を任意に設定することによっても最適な位置に固定可能である。   By moving the ferrite core 10 and the ferrite core fixture 1 with respect to the flat cable 12, the ferrite core 10 can be fixed at an optimum position. Moreover, it can fix to an optimal position also by setting the length or shape of the to-be-fixed part 3 of the ferrite core fixing tool 1 arbitrarily.

フェライトコア１０を取り外す場合は上記の動作を逆に行えばよい。すなわち、フェライトコア固定具１の被固定部３におけるネジを取り外し、フェライトコア固定具１を取付け対象から取り外す。そしてフェライトコア固定具１の両腕部５、６を窄めてフェライトコア固定具１をフェライトコア１０の中空部１１から抜き取ることにより、取り外しを行う。   When removing the ferrite core 10, the above operation may be reversed. That is, the screw in the fixed portion 3 of the ferrite core fixture 1 is removed, and the ferrite core fixture 1 is removed from the attachment target. Then, the arms 5 and 6 of the ferrite core fixture 1 are narrowed and the ferrite core fixture 1 is removed from the hollow portion 11 of the ferrite core 10 to be removed.

またフェライトコア１０を取り外す場合、フェライトコア固定具１を取付け対象に固定した状態でフェライトコア１０をフェライトコア固定具１から引き抜くようにようにしてもフェライトコア１０およびフラットケーブル１２の取り外しは可能である。特に取付け対象である装置にメインテナンスが必要な場合に、固定具１を装置に固定したままでフェライトコア１０だけ取り外すことにより、メインテナンスを容易に行うことができる。   When the ferrite core 10 is removed, the ferrite core 10 and the flat cable 12 can be detached even if the ferrite core 10 is pulled out from the ferrite core fixture 1 with the ferrite core fixture 1 fixed to the attachment target. is there. In particular, when maintenance is required for the device to be attached, maintenance can be easily performed by removing only the ferrite core 10 while the fixture 1 is fixed to the device.

以上のように第１の実施の形態によれば、フェライトコア１０の中空部１１にフェライトコア固定具１の保持部２を差し込むだけでフェライトコア１０を保持でき、フェライトコア固定具１の被固定部３で取付け対象に固定するので、容易にフェライトコア１０を固定することができる。またフェライトコア固定具１がフィルムシート状の平板形から構成されているので、製造上、専用の金型を必要とせず、安価な製造が可能であるとともに、フラットケーブル１２が撓んでいる場合でもその撓みに合わせてフェライトコア固定具１がある程度変形することが可能であり、フラットケーブル１２が撓む位置での固定が可能である。   As described above, according to the first embodiment, the ferrite core 10 can be held only by inserting the holding portion 2 of the ferrite core fixture 1 into the hollow portion 11 of the ferrite core 10, and the ferrite core fixture 1 is fixed. Since it fixes to the attachment object in the part 3, the ferrite core 10 can be fixed easily. In addition, since the ferrite core fixture 1 is composed of a film sheet-like flat plate, it does not require a dedicated mold for manufacturing, and can be manufactured at low cost, and even when the flat cable 12 is bent. The ferrite core fixture 1 can be deformed to some extent according to the bending, and can be fixed at the position where the flat cable 12 is bent.

さらに、フェライトコア固定具１の被固定部３の長さ又は形状を任意に設定可能であり、またネジ孔７の位置も任意に設定可能であるので、取付け対象の最適な位置にフェライトコア１０を固定することが可能になる。   Further, since the length or shape of the fixed portion 3 of the ferrite core fixture 1 can be arbitrarily set, and the position of the screw hole 7 can be arbitrarily set, the ferrite core 10 can be placed at the optimum position to be attached. Can be fixed.

次に参考例１を説明する。図８は参考例１のフェライトコア固定部を示す斜視図である。図８において、参考例１のフェライトコア固定具３１は、第１の実施の形態と同様に、フィルムシート状の平板形をした弾性部材から構成され、保持部３２と被固定部３３とから構成される。保持部３２は、中央保持部３４とその両側に折り曲げ可能に形成された一対の腕部３５、３６とを有する。両腕部３５、３６の基部にはそれぞれ角孔３５ａ、３６ａが形成されており、腕部３５の先端部にはカギ爪部３５ｂが形成され、他方の腕部３６には切り込み部３６ｃを有する角孔３６ｂが形成されている。カギ爪部３５ｂは、切り込み部３６ｃに挿入可能であり、カギ爪部３５ｂの基部３５ｃが腕部３６の角孔３６ｂに入り込むことにより、腕部３５と腕部３６が互いに係止される。
Next, Reference Example 1 will be described. FIG. 8 is a perspective view showing a ferrite core fixing portion of Reference Example 1. FIG. In FIG. 8, the ferrite core fixture 31 of Reference Example 1 is constituted by a film sheet-like flat plate-like elastic member as in the first embodiment, and is constituted by a holding portion 32 and a fixed portion 33. Is done. The holding part 32 includes a central holding part 34 and a pair of arm parts 35 and 36 formed to be foldable on both sides thereof. Square holes 35a and 36a are formed at the base portions of both arm portions 35 and 36, respectively, a hook claw portion 35b is formed at the distal end portion of the arm portion 35, and the other arm portion 36 has a cut portion 36c. A square hole 36b is formed. The key claw portion 35b can be inserted into the cut portion 36c, and when the base portion 35c of the key claw portion 35b enters the square hole 36b of the arm portion 36, the arm portion 35 and the arm portion 36 are locked to each other.

角孔３５ａ、３６ａの高さは、フェライトコア１０の厚さより僅かに大きく設定され、角孔３５ａ、３６ａの幅（図８における縦方向の長さ）は、フェライトコア１０の長さよりも僅かの大きく設定されている。そのためフェライトコア１０は角孔３５ａ、３６ａの中に入り込むことができる。中央保持部３４の幅（両腕部３５、３６間の距離）は、フラットケーブル１２より僅かに大きい幅を有し、かつフェライトコア１０の幅より若干短く設定されている。   The height of the square holes 35a, 36a is set slightly larger than the thickness of the ferrite core 10, and the width of the square holes 35a, 36a (the length in the vertical direction in FIG. 8) is slightly smaller than the length of the ferrite core 10. It is set large. Therefore, the ferrite core 10 can enter the square holes 35a and 36a. The width of the center holding portion 34 (distance between both arm portions 35 and 36) is slightly larger than the flat cable 12 and is set slightly shorter than the width of the ferrite core 10.

中央保持部３４の両側にはまた曲げ起こし部３７、３８がそれぞれ角孔３５ａ、３６ａに入り込むように形成されており、曲げ起こし部３７、３８の長さはフェライトコア１０の長さとほぼ同じに設定されている。一方の曲げ起こし部３７から他方の曲げ起こし部３８までの長さは、フェライトコア１０の幅とほぼ同じに設定されている。被固定部３３には、第１の実施の形態と同様に、フラットケーブルが配置される位置から片側へずれた位置にネジ孔７が形成されている。   Bending portions 37 and 38 are formed on both sides of the central holding portion 34 so as to enter the square holes 35a and 36a, respectively. The lengths of the bending raising portions 37 and 38 are substantially the same as the length of the ferrite core 10. Is set. The length from one bent raised portion 37 to the other bent raised portion 38 is set to be substantially the same as the width of the ferrite core 10. As in the first embodiment, the fixed portion 33 is formed with a screw hole 7 at a position shifted to one side from the position where the flat cable is arranged.

次に参考例１におけるフェライトコア固定動作を説明する。図９、図１０は参考例１におけるフェライトコア固定動作を示す斜視図である。両図において、中空部１１にフラットケーブル１２を貫通したフェライトコア１０に対して、フェライトコア固定具３１の中央保持部３４を当て、図９に示すように、両方の腕部３５、３６を折り曲げる。このときフェライトコア１０の両側部は角孔３５ａ、３６ａに入り込むので、腕部３５、３６は容易に折り曲げられる。またこのときフェライトコア１０は曲げ起こし部３７、３８の間に保持され、これによりフェライトコア１０は左右方向への動きを規制される。両腕部３５、３６を折り曲げることにより、フェライトコア１０は上下方向への動きを規制される。
Next, the ferrite core fixing operation in Reference Example 1 will be described. 9 and 10 are perspective views showing the ferrite core fixing operation in Reference Example 1. FIG. In both figures, the center holding part 34 of the ferrite core fixture 31 is applied to the ferrite core 10 that has penetrated the flat cable 12 into the hollow part 11, and both arm parts 35 and 36 are bent as shown in FIG. . At this time, since both side portions of the ferrite core 10 enter the square holes 35a and 36a, the arm portions 35 and 36 are easily bent. Further, at this time, the ferrite core 10 is held between the bent raised portions 37 and 38, whereby the ferrite core 10 is restricted from moving in the left-right direction. By bending both arm portions 35 and 36, the ferrite core 10 is restricted from moving up and down.

次に腕部３５のカギ爪部３５ｂを腕部３６の切り込み部３６ｃに挿入し、さらにカギ爪部３５ｂの基部３５ｃを角孔３６ｂに入り込ませ、図１０に示す状態にする。これによりフェライトコア１０を保持した状態で、腕部３５と腕部３６が互いに係止される。   Next, the key claw portion 35b of the arm portion 35 is inserted into the cut portion 36c of the arm portion 36, and the base portion 35c of the key claw portion 35b is inserted into the square hole 36b to obtain the state shown in FIG. Thus, the arm portion 35 and the arm portion 36 are locked with each other while the ferrite core 10 is held.

次に第１の実施の形態の場合と同様に、フェライトコア固定具３１の被固定部３３に形成されたネジ孔７を使用して取付け対象にフェライトコア固定具３１をネジ固定する。   Next, as in the case of the first embodiment, the ferrite core fixture 31 is screwed to the attachment target using the screw holes 7 formed in the fixed portion 33 of the ferrite core fixture 31.

フェライトコア１０を取り外す場合は上記の動作を逆に行えばよい。すなわち、フェライトコア固定具３１の被固定部３３におけるネジを取り外し、フェライトコア固定具３１を取付け対象から取り外す。そしてフェライトコア固定具３１の腕部３５のカギ爪部３５ｂを腕部３６の角孔３６ｂから抜き出し、両腕部３５、３６を広げてフェライトコア１０の保持状態を解除する。また、フェライトコア固定具３１を取付け対象に固定したままで、フェライトコア１０およびフラットケーブル１２のみ取り外すようにしてもよい。   When removing the ferrite core 10, the above operation may be reversed. That is, the screw in the fixed portion 33 of the ferrite core fixture 31 is removed, and the ferrite core fixture 31 is removed from the attachment target. Then, the key claw portion 35b of the arm portion 35 of the ferrite core fixture 31 is extracted from the square hole 36b of the arm portion 36, and both the arm portions 35 and 36 are widened to release the holding state of the ferrite core 10. Moreover, you may make it remove only the ferrite core 10 and the flat cable 12 with the ferrite core fixing tool 31 fixed to the attachment object.

以上のように参考例１によれば、上記第１の実施の形態の有する効果に加えて、フェライトコア１０を外側から保持するようにしたので、フェライトコア１０の中空部１１の大きさに関係なくフェライトコア１０を固定することができる。またフェライトコア１０を上下方向へも左右方向へも移動しないように保持するので、取付け対象である装置の振動や衝撃等によりフェライトコア１０が近隣の部品と直接接触することにより破損を防止することができる。さらに、両腕部３５、３６を係止するだけでフェライトコア１０を保持できるので、保持動作が極めて容易である効果がある。
As described above, according to the reference example 1 , in addition to the effect of the first embodiment, the ferrite core 10 is held from the outside, so that it is related to the size of the hollow portion 11 of the ferrite core 10. Therefore, the ferrite core 10 can be fixed. Further, since the ferrite core 10 is held so as not to move in the vertical direction and the horizontal direction, the ferrite core 10 is prevented from being damaged by directly contacting with neighboring parts due to vibration or impact of the device to be attached. Can do. Furthermore, since the ferrite core 10 can be held only by locking both the arm portions 35 and 36, there is an effect that the holding operation is extremely easy.

次に参考例２を説明する。図１１は参考例２のフェライトコア固定具を示す斜視図である。図１１において、参考例２のフェライトコア固定具４１は、参考例１と同様に、フィルムシート状の平板形をした弾性部材から形成され、保持部４２と被固定部４３とから構成される。保持部４２は、中央保持部４４とその両側に折り曲げ可能に形成された一対の腕部４５、４６とを有する。両腕部４５、４６の基部にはそれぞれ角孔４５ａ、４６ａが形成されており、腕部４５の先端部にはカギ爪部４５ｂが形成され、他方の腕部４６には切り込み部４６ｃを有する角孔４６ｂが形成されている。カギ爪部４５ｂは、切り込み部４６ｃに挿入可能であり、カギ爪部４５ｂの基部４５ｃが腕部４６の角孔４６ｂに入り込むことにより、腕部４５と腕部４６が互いに係止される。
Next, Reference Example 2 will be described. FIG. 11 is a perspective view showing a ferrite core fixture of Reference Example 2. FIG. In FIG. 11, the ferrite core fixture 41 of Reference Example 2 is formed of a film sheet-like flat plate-like elastic member as in Reference Example 1, and includes a holding portion 42 and a fixed portion 43. The holding part 42 has a central holding part 44 and a pair of arm parts 45 and 46 formed to be foldable on both sides thereof. Square holes 45a and 46a are formed at the base portions of both arm portions 45 and 46, respectively, a hook claw portion 45b is formed at the distal end portion of the arm portion 45, and the other arm portion 46 has a cut portion 46c. A square hole 46b is formed. The key claw portion 45b can be inserted into the cut portion 46c, and when the base portion 45c of the key claw portion 45b enters the square hole 46b of the arm portion 46, the arm portion 45 and the arm portion 46 are locked to each other.

参考例１と同様に、角孔４５ａ、４６ａの高さは、フェライトコア１０の厚さより僅かに大きく設定され、角孔４５ａ、４６ａの幅（図１１における縦方向の長さ）は、フェライトコア１０の長さよりも僅かの大きく設定されている。そのためフェライトコア１０は角孔４５ａ、４６ａの中に入り込むことができる。中央保持部４４の幅（両腕部４５、４６間の距離）は、フラットケーブル１２より僅かに大きい幅を有し、かつフェライトコア１０の幅より若干短く設定されている。
Similar to Reference Example 1 , the height of the square holes 45a, 46a is set slightly larger than the thickness of the ferrite core 10, and the width of the square holes 45a, 46a (the length in the vertical direction in FIG. 11) is the ferrite core. It is set slightly larger than the length of 10. Therefore, the ferrite core 10 can enter the square holes 45a and 46a. The width of the central holding portion 44 (distance between both arm portions 45 and 46) is set to be slightly larger than the flat cable 12 and slightly shorter than the width of the ferrite core 10.

中央保持部４４の両側には２種類の曲げ起こし部４５ｄ、４５ｅ、４６ｄ、４６ｅが段違いにそれぞれ角孔３５ａ、３６ａに入り込むように形成されている。一方の曲げ起こし部４５ｅから他方の曲げ起こし部４６ｅまでの長さは、フェライトコア１０の幅より僅かに大きく設定されており、フェライトコア１０を外側から抱え込むことによりフェライトコア１０が左右方向に抜き出ることを防止する。またもう一種類の曲げ起こし部４５ｄと曲げ起こし部４６ｄは、互いの間の距離は腕部４５、４６間の距離とほぼ同じで、高さは曲げ起こし部４５ｅ、４６ｅより低く設定されている。そのため、フェライトコア１０を保持部４２で保持する際にフェライトコア１０の側面部で押し潰される状態になる。曲げ起こし部４５ｄ、４６ｄは、後述する小さい種類のフェライトコアを保持する際に該フェライトコアの移動を規制するために形成されたものである。   Two kinds of bending raising portions 45d, 45e, 46d, and 46e are formed on both sides of the central holding portion 44 so as to enter the square holes 35a and 36a, respectively. The length from one bent raised portion 45e to the other bent raised portion 46e is set to be slightly larger than the width of the ferrite core 10. By holding the ferrite core 10 from the outside, the ferrite core 10 is pulled out in the left-right direction. Prevent exiting. In addition, the other kind of the bent raised portion 45d and the bent raised portion 46d have a distance between them that is substantially the same as the distance between the arm portions 45 and 46, and the height is set lower than the bent raised portions 45e and 46e. . Therefore, when the ferrite core 10 is held by the holding portion 42, the ferrite core 10 is crushed by the side surface portion. The bent raised portions 45d and 46d are formed to restrict the movement of the ferrite core when holding a small type of ferrite core described later.

被固定部４３には、第１の実施の形態と同様に、フラットケーブルが配置される位置から片側へずれた位置にネジ孔７が形成されている。   As in the first embodiment, the fixed portion 43 is formed with a screw hole 7 at a position shifted to one side from the position where the flat cable is arranged.

次に参考例２におけるフェライトコア固定動作を説明する。図１２乃至図１４は参考例２におけるフェライトコア固定動作を示す斜視図である。参考例２では、高さ方向の大きさの異なる２種類のフェライトコアを固定する動作を説明する。まず高さの高いフェライトコアを固定する場合を説明する。
Next, the ferrite core fixing operation in Reference Example 2 will be described. 12 to 14 are perspective views showing the ferrite core fixing operation in Reference Example 2. FIG. In Reference Example 2 , an operation of fixing two types of ferrite cores having different sizes in the height direction will be described. First, a case where a high ferrite core is fixed will be described.

図１２において、中空部１１にフラットケーブル１２を貫通したフェライトコア１０に対して、フェライトコア固定具４１の中央保持部４４を当て、両方の腕部４５、４６を折り曲げる。このときフェライトコア１０の両側部は角孔４５ａ、４６ａに入り込むので、腕部４５、４６は容易に折り曲げられる。またこのときフェライトコア１０は曲げ起こし部４５ｅ、４６ｅの間に保持され、これによりフェライトコア１０は左右方向への動きを規制される。このときフェライトコア１０は、曲げ起こし部４５ｄ、４６ｄの上に乗った状態になる。両腕部４５、４６を折り曲げることにより、フェライトコア１０は上下方向への動きを規制される。このとき曲げ起こし部４５ｄ、４６ｄの弾性力によりフェライトコア１０は圧接状態に保持される。   In FIG. 12, the center holding portion 44 of the ferrite core fixture 41 is applied to the ferrite core 10 that penetrates the flat cable 12 through the hollow portion 11, and both arm portions 45 and 46 are bent. At this time, since both side portions of the ferrite core 10 enter the square holes 45a and 46a, the arm portions 45 and 46 are easily bent. At this time, the ferrite core 10 is held between the bent raised portions 45e and 46e, and thereby the ferrite core 10 is restricted from moving in the left-right direction. At this time, the ferrite core 10 is put on the bent raised portions 45d and 46d. By bending both arm portions 45 and 46, the ferrite core 10 is restricted from moving up and down. At this time, the ferrite core 10 is held in a pressure contact state by the elastic force of the bent raised portions 45d and 46d.

次に腕部４５のカギ爪部４５ｂを腕部４６の切り込み部４６ｃに挿入し、さらにカギ爪部４５ｂの基部４５ｃを角孔４６ｂに入り込ませ、図１３に示す状態にする。これによりフェライトコア１０を保持した状態で、腕部４５と腕部４６が互いに係止される。   Next, the key claw portion 45b of the arm portion 45 is inserted into the cut portion 46c of the arm portion 46, and further, the base portion 45c of the key claw portion 45b is inserted into the square hole 46b to obtain the state shown in FIG. Thus, the arm portion 45 and the arm portion 46 are locked with each other while the ferrite core 10 is held.

次に第１の実施の形態の場合と同様に、フェライトコア固定具４１の被固定部４３に形成されたネジ孔７を使用して取付け対象にフェライトコア固定具４１をネジ固定する。   Next, as in the case of the first embodiment, the ferrite core fixture 41 is screwed to the attachment target using the screw holes 7 formed in the fixed portion 43 of the ferrite core fixture 41.

次に高さの低いフェライトコアを固定する場合について説明する。図１４において、高さの低いフェライトコア１４は曲げ起こし部４５ｅと曲げ起こし部４６ｅとの間に保持される。すなわち、曲げ起こし部４５ｅ、４６ｅの長さは、高さに低いフェライトコア１４の高さに合わせた寸法に設定されている。このとき曲げ起こし部４５ｄ、４６ｄは、曲げ起こし部４５ｅ、４６ｅよりも互いの間隔が狭く設定されているので、保持した状態においてフェライトコア１４の上方向への移動を規制する。すなわち、高さの低いフェライトコア１４を保持する場合でも、フェライトコア１４を上下方向および左右方向に動きを規制することができるようになっている。   Next, the case where a low ferrite core is fixed will be described. In FIG. 14, the ferrite core 14 having a low height is held between the bent raised portion 45e and the bent raised portion 46e. That is, the lengths of the bent raised portions 45e and 46e are set to dimensions that match the height of the ferrite core 14 that is low in height. At this time, since the bend-raised portions 45d and 46d are set to be narrower than the bend-raised portions 45e and 46e, the upward movement of the ferrite core 14 is restricted in the held state. That is, even when the ferrite core 14 having a low height is held, the movement of the ferrite core 14 can be restricted in the vertical direction and the horizontal direction.

フェライトコア１０または１４を取り外す場合は上記の動作を逆に行えばよい。すなわち、フェライトコア固定具４１の被固定部４３におけるネジを取り外し、フェライトコア固定具４１を取付け対象から取り外す。そしてフェライトコア固定具４１の腕部４５のカギ爪部４５ｂを腕部４６の角孔４６ｂから抜き出し、両腕部４５、４６を広げてフェライトコア１０または１４の保持状態を解除する。また、フェライトコア固定具４１を取付け対象に固定したままで、フェライトコア１０または１４およびフラットケーブル１２のみ取り外すようにしてもよい。   When removing the ferrite core 10 or 14, the above operation may be reversed. That is, the screw in the fixed portion 43 of the ferrite core fixture 41 is removed, and the ferrite core fixture 41 is removed from the attachment target. Then, the key claw portion 45b of the arm portion 45 of the ferrite core fixture 41 is extracted from the square hole 46b of the arm portion 46, and both arm portions 45 and 46 are widened to release the holding state of the ferrite core 10 or 14. Moreover, you may make it remove only the ferrite core 10 or 14 and the flat cable 12 with the ferrite core fixing tool 41 fixed to the attachment object.

以上のように参考例２によれば、参考例１の有する効果に加えて、フェライトコアを保持するための曲げ起こし部を２種類段違いに設けたことにより、高さの異なる２種類のフェライトコアを固定することが可能となる。その結果、フェライトコアの大きさに合わせたフェライトコア固定具を個別に用意する必要がなく、部品の管理や物流の管理が煩雑にならないで済むという効果がある。さらに、２種類のフェライトコアに対して共通的に使用することができることから、フェライトコア固定具の単価を低減することが可能となる。
As described above, according to Reference Example 2 , in addition to the effects of Reference Example 1 , two types of ferrite cores having different heights are provided by providing two kinds of bending raising portions for holding the ferrite core. Can be fixed. As a result, there is an effect that it is not necessary to separately prepare a ferrite core fixture according to the size of the ferrite core, and the management of parts and the management of physical distribution are not complicated. Furthermore, since it can be commonly used for two types of ferrite cores, the unit price of the ferrite core fixture can be reduced.

上記各実施の形態では、コア部材固定具としてフェライトコアを固定する固定具で説明したが、本発明はこれに限らず、ケーブルを貫通してケーブル上に設置する部材であれば他の部材に対しても適用可能である。   In each of the above embodiments, the fixing member for fixing the ferrite core has been described as the core member fixing tool. However, the present invention is not limited to this, and any member that penetrates the cable and is installed on the cable may be used. It can also be applied to.
